[Boost-users] serialization error : boost_serialization not closed

Dear Users, I am often incurring in an error when I try to load the xml objects serialized with boost with an xml reader (notepad 2007 for example) . The error message is always the following "The following elements are not closed: boost_serialization". In the case of vector<double> the serialized file reads like this: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <count>777</count> 0 <item>0.654941</item> <item>0.61598900000000001</item> <item>0.051253</item> <item>0.03968</item> ... Then apparently there is boost_serialization is not closed (however, the deserialization with boost will work). Am I wrong somewhere or is it truly an issue? Thanks in advance
